Malacostegina Levinsen 1902

A closer view of one of the colonies shows the lacelike latticework of the boxlike zooecia.

This closer view of the same colony as above shows the small spines present around some of the zooids. Perhaps this colony has been attacked by nudibranchs lately.

This closeup view of a colony wrapped around a tiny Nereocystis stipe shows the feeding zooids with their lophophores extended in the feeding position.

Here is a closer view of the lophophores.
